8031389: On x86 C1 emits two relocations for polls
Summary: C1 emits two poll_type relocations at safepoint polls because LIR_Assembler::safepoint_poll(..) adds a relocation and calls LIR_Assembler::add_debug_info_for_branch(..) which adds a relocation as well. The implementation of add_debug_info_for_branch(..) is changed to not emit a poll relocation.
